NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE
CITY OF DANVILLE that:
A. The City hereby finds and certifies that the Final EIR
has been completed in compliance with the California
Environmental Quality Act, as amended ("CEQA"), and the State
EIR Guidelines, and that the City has reviewed and considered
the information contained in the Final EIR prior to making a
decision on the Project.
B. In accordance with Section 15091 of the State EIR
Guidelines, the City finds that the project will have the
following significant impacts and makes findings regarding their
mitigation to acceptable levels:
1. Geology and Topography
a. Impacts
i
1.
Proposed grading on the southwest limb of the
Tassajara syncline would increase the potential
for slope instability in the area.
ii.
Grading of the site resulting in exposed soil and
cut slopes would increase erosion hazards.
iii. Proposed cut and fill operations in the four slide
areas identified as sections A through D on page
16 of the DEIR would result in significant changes
in the stability of the affected slopes.
iv.
Ground water saturation of geologic material would
reduce stability of surface deposits in areas that
receive fill, especially gullies, swales, and
steep slopes.
Va
Settlement of fill due to consolidation of fill
material could result in damage to foundations and
structures.
b. Mitigation measures:
i
1.
Mitigation measures contained on pages 19 and 20
of the Draft EIR are hereby incorporated as
conditions of project approval except as modified
below.
ii.
The City finds that changes in project design have
addressed a portion of the mitigation measures
cited above. These mitigation measures are deemed
to have been satisfied through adoption of this
resolution, specifically referencing proposed
mitigation measures 1,2, and 3.
·
iii. Mitigation measure # 5 contained on page 26 of the
Revised Responses to Comments document (comment
#86) is hereby incorporated as a condition at
project approval.
Drainage
a. Impacts
i.
Bank erosion could damage properties located too
close to streams.
ii.
Storm runoff could cause sediment related problems
resulting in blockage of flood control works as
well as cosmetic damage to residential areas.
iii. Water quality may be adversely affected by
suspended sediment caused by runoff·
b. Mitigation measures:
i·
Mitigation measures contained on pages 23 and 24
of the Draft EIR and on page 1 of the Revised
Response to Comments document (comment 1) are
hereby incorporated as conditions of project
approval except as modified below.
ii. Mitigation measure #3 in page 23 of the Draft EIR
is revised to state that grading operations should
be completed prior to October 15 rather than prior
to the start of the rainy season.
iii. Mitigation measure #7 contained on page 24 of the
Draft EIR is amended to include the additional
language contained in page 6 of the Revised
Response to Comments document (comment #18).
iv. The mitigation measure contained on page 27 of the
Revised Response to Comments document (comment
#88) is hereby incorporated as a condition at
project approval.
3. Vegetating and Wildlife
a. Impacts:
i·
Removal of oak trees and snags within the
development portion of the site would eliminate a
source of food, perch sites and nest sites for
species associated with oak savannah and riparian
woodland.
ii.
The existing stream bed would be altered resulting
in the loss of oak and willow trees within the
natural channel·
iii. Wildlife associated with the riparian habitat
would be largely eliminated.
iv.
Trees to be preserved in open space areas may
sustain damage form grading operations.
b. Mitigation measures:
io
Mitigation measures contained on pages 30 and 32
of the Draft EIR are hereby incorporated as
conditions of project approval except as modified
below:
ii.
The City finds that Mitigation measure # 9 stated
a page 32 of the DEIR is not appropriate due to
changes in project design that lessen or eliminate
the potential impact for which mitigation was
recommended.
iii. Mitigation measure #5 on page 32 of the Draft EIR
revised to read: "A buffer zone averaging 50 feet
wide should be ..."
iv. The mitigation measure contained on page 26 of the
Revised Response to Comments document (comment
#86) is hereby incorporated as a condition at
project approval.
4. Climate and Air quality:
a. Impacts
i.
Normal construction activities will result in an
increase in dust and suspended particles in the
project area.
ii.
Vehicle use in the development will add to ozone
and carbon monoxide levels in the immediate area.
be
Mitigation Measures: Mitigation measures contained on
page 37 of the Draft EIR are hereby incorporated as
conditions of project approval.
.
Noise:
a. Impacts:
ie
Traffic noise generated by the development on
adjacent roads would not exceed standard
acceptable levels.
ii.
Residences along E1 Ca, on, McCauley Road and
Redondo Way would be disturbed by increased noise
levels due to construction activities and use of
heavy equipment.
be
Mitigation Measures: The mitigation measure contained
on pages 40 of the Draft EIR is hereby incorporated as
a condition of project approval.
6. Visual Quality:
a. Impacts:
i.
Views of the project site would change from
undeveloped hillsides and valley bottom to a
residential subdivision.
ii.
The predominant two story nature of the proposed
homes would contrast with the predominately one
story homes in the existing subdivision.
iii. The project will appear more dense than the
surrounding subdivision due to the majority of the
homes having two stories, and due to the inclusion
of the patio homes.
be
Mitigation measures: Mitigation measures contained on
pages 52 and 53 of the Draft EIR are hereby
incorporated as conditions of project approval.
7. Traffic and Circulation
a. Impacts:
i.
Project traffic would increase the need for
signals at Diablo Road/Camino Tassajara, Diablo
Road/Green Valley Road and Diablo Road/E1 Cerro
Boulevard intersections.
ii.
The increase in traffic due to development would
pose safety problems to elementary school students
using E1 Ca, on Drive, McCauley Road and Diablo
Road.
iii. Site distances from driveways on proposed lots
#74-76 located on "A" Drive could be limited.
iv.
The large number of intersections along "A" Drive
could pose safety hazards due to traffic conflicts
between turning vehicles and through traffic.
Vo
The proposed 40 foot width of "A" Drive would not
be adequate if parking were allowed on both sides
of the street.
vi.
The increase in traffic due to development would
contribute to the deterioration of level of
service on the following street segments:
o E1 Cerro Blvd. between 1-680 and Diablo Rd.
o Diablo Road between Camino Tassajara and
E1 Cerro Blvd.
o Diablo Road between E1 Cerro Blvd. and
Green Valley Rd.
b. Mitigation measures:
i.
Mitigation measures contained on pages 61 through
63 of the Draft EIR are hereby incorporated as
conditions of project approval except as modified
or supplemented below.
ii.
The City finds that extension of E1 Cajon Drive to
intersect with McCauley Road would be disruptive
to the existing residential neighborhood and that
preventing such disruption outweighs the advantage
of extending the street.
iii. As a result of E1 Cajon Drive not being extended
to intersect with McCauley Road, McCauley Road
should be improved as a full two way street
including parking, pedestrian, bicycle and
landscaping improvements as determined by the
City.
iv. The project sponsor should contribute their share
as determined by the City toward capacity related
improvements along the following roadway segments:
o Diablo Road between Camino Tassajara and E1
Cerro Boulevard.
o E1 Cerro Boulevard between 1-650 and Diablo
Road.
v. The project sponsor should be required to post a
bond with the City for street repair and
maintenance during project development.
vi. Mitigation measure #5 on page 62 of the Draft EIR
is amended to read, "Bicycle lanes and sidewalks
should be provided along McCauley Road through the
site and extending to Diablo Road to minimize
potential safety problems".
vii. Mitigation measure #7 on page 62 of the Draft EIR
is revised to read, "Orientation of driveways for
proposed lots 74-76 should take into account
limited sight distances created by the curve at
'A' Drive in that location.
viii. The mitigation measure contained on page 27 of the
Revised Response to Comments document (comment
#89) is hereby incorporated as a condition of
project approval.
8. Water Service
a.
Impacts: Development of the project would require
service from the Danville Pressure Zone for lots below
450 feet elevation, and Diablo Pressure Zone for lots
between 450 and 650 feet in elevation. Water service
to lots in the Diablo Pressure Zone is contingent on
expansion in capacity of the water storage and
distribution system.
bw
Mitigation measures: Mitigation measures contained on
page 65 of the Draft EIR are hereby incorporated as
condition at project approval.
9. Wastewater Collection and Treatment:
a. Impacts:
i. Development of the project would necessitate the
treatment of additional wastewater by the Pacheco
Sewage Plant, totalling approximately .25 percent
of its present capacity.
f
be
ii. Depending on which of two adjacent trunk sewers is
utilized by the project enlargement of certain
sections may be required.
Mitigation measures: Mitigation measures contained on
page 66 of the Draft EIR and on page 3 of the Revised
Response to Comments document (comment #9) are hereby
incorporated as conditions at project approval.
10. Fire Service:
a. Impacts
be
a.
be
11.
ae
12.
b.
i. Existing equipment and manpower levels are
sufficient to service the proposed project.
ii. Proposed project location in a dry grass area
raised concern about fire danger.
Mitigation measures: Mitigation measures contained on
pages 68 and 69 of the Draft EIR and on page 27 of the
Revised Response to Comments document (comment #87) are
hereby incorporated as conditions at project approval.
Police Services
Impacts:
i. The project would not have a direct impact on
police manpower or equipment requirements.
ii. Increases in theft and vandalism is expected on
the project site during the construction period.
Mitigation measure: The mitigation measure contained
on page 67 of the Draft EIR is hereby incorporated as a
condition of project approval.
Schools:
Impacts: The estimated increase in school age children
will cause additional pressure on the adjacent schools
which are near or over-capacity now.
Mitigation measures:
i. The City finds that adoption of the mitigation
measure contained on page 70 of the Draft EIR is
not appropriate due to the specific nature of the
mitigation measure, and due to uncertainty which
currently exists statewide with regard to
financing of permanent school facilities.
/~/~
ii. In lieu of the mitigation measure recommended in
the Draft EIR, the project sponsor should be
required to pay impact fees to the San Ramon
Valley Unified School District in an amount
determined by the School District to offset the
projects impact on existing school facilities
and/or to fund the construction of additional
schools if needed·
13. No significant environmental impacts were identified, and
consequently no mitigation measures are recommended for Gas
and Electric Service, Telephone Services, and Solid Waste
Disposal·
C. Due to potential impacts identified in the EIR and
concerns expressed during the public hearings of the Planning
Commission with regard to the project design, certain changes
have been made in the proposed project design· These changes
serve to satisfy a portion of the mitigation measures specified
in paragraph B of this resolution and to lessen environmental
impacts identified in the EIR. The City finds as follows with
regard to the various changes:
l·
Visual quality of the project will be enhanced due to a
reduction in the height and extent of graded slopes
throughout the development·
·
The creek and its riparian area will be enhanced by
removing proposed lots from close proximity to its
banks through a larger portion of the creek. A greater
portion of the creek will be left in its current
alignment accompanied by creek enhancement
improvements·
·
Areas identified in the EIR as geologically unstable
have been avoided and others have been redesigned to
better respond to the geologic conditions·
·
The patio home area has been removed from the front
portion of the site adjacent to the creek and has been
relocated to a portion of the site further removed from
the existing residential subdivision. In order to
create the necessary area for development of the patio
home neighborhood, the grading plan was modified
resulting in a significant cut and fill area in the
north central portion of the site. Potential impacts
associated with this grading are as follows:
ae
Modification of the existing land from through
both cut and fill may result in geologic
instability in the area.
be
Creation of an area of development in the lower
portion of a valley may result in drainage impacts
associated with upstream drainage and runoff from
the adjacent slopes·
C.
The extent of the cut slope proposed may result in
visual quality impacts resulting from the height
and engineered appearance of the graded area.
Mitigation measures cited in previous paragraphs of
this resolution apply to these impacts and will result
in their reduction to acceptable levels.
D. Pursuant to Section 15091 of the State EIR Guidelines,
the City finds that implementation of the project will have the
following significant impacts which are unavoidable:
l·
Permanent loss of open space, wildlife habitat value
and native vegetation.
·
Deterioration of traffic conditions due to cumulative
increases in traffic volumes·
·
Cumulative degradation of air quality and increased
noise levels in Danville due to cumulative traffic
volumes.
·
Short term effects such as the generation of dust and
increased noise levels due to construction activities·
·
Temporary increase in stream sediment loads and
creation of a permanent source for urban pollutants in
surface runoff·
Pursuant to Section 15093 of the State EIR Guidelines, the City
finds as follows regarding the significant unavoidable
environmental impacts:
~
The permanent loss of open space, wildlife habitat
value and native vegetation is allowed to occur due to
the fact that only 66 acres of the site is proposed for
development with the remaining 242 acres to be
maintained in permanent open space· Included in the
permanent open space is a major ridgeline which is a
major geographic feature visible throughout the region.
·
Cumulative deterioration of traffic conditions in the
region is allowed to occur due to satisfaction of a
portion of the regions housing needs, and due to
conditions of development approval which require
improvement of streets which serve the project, located
primarily off-site, extending to 1-680.
D·
·
Cumulative and short term effects related to
degradation of air quality, increased noise levels,
generation of dust due to construction activity, and
temporary increases of stream sediment loads are
allowed to occur due to the designation of the property
for development since prior to incorporation of the
City, the existence of developed properties immediately
adjacent to the project and due to beneficial impacts
resulting from the project related to traffic
improvements to be funded by the project sponsor,
preservation of a substantial portion of the site in
open space, and the provision of housing for the
community.
Upon approval of the Project by the City Council, the
City Clerk is hereby directed to file a Notice of
Determination with the County Clerk of Contra Costa
County pursuant to the provisions of Section 21152 of
the Public Resources Code and the State EIR Guidelines
adopted pursuant thereto·
